ANSWERS
◉ What is the normal fat-to-cell ratio in an adult bone marrow. Answer:
50:50
◉ Which cell type forms more bone. Answer: Osteoblast
◉ Which cell type destroys bone. Answer: Osteoclast
◉ Which of the following cells has self-renewal?
Segmented neutrophil
Promyelocyte
Orthochromic normoblast
Pluripotential stem cell. Answer: Pluripotential stem cell
◉ Where are bone marrow aspirates usually performed on adults.
Answer: Posterior superior iliac crest
,◉ True or False: The spicules on a bone marrow slide are what we use to
perform the differential.. Answer: True
◉ What is the normal range for megakaryocytes in the bone marrow.
Answer: 2-10/lpf
◉ What is the normal bone marrow cellularity for children. Answer:
80%
◉ What is the normal bone marrow cellularity for adults (ages 30-70).
Answer: 50%
◉ How do you calculate the normal bone marrow cellularity for people
>70 years old. Answer: 100% - Patient Age = cellularity +/- 10%
ex. Patient is 80.
100% - 80 = 20% +/- 10% (Range of 10-30%)
◉ Can the bone marrow differential be performed from the biopsy.
Answer: No
◉ How many cells are counted on a bone marrow differential. Answer:
500-1000 cells
, ◉ What is the normal Myeloid:Erythroid (M:E) ratio. Answer: 3:1
(There should be about 3 times more myeloid cells than erythroid cells)
◉ True or False: Lymphocytes are not included in the M:E ratio..
Answer: True
◉ What is the average life span of myeloid cells. Answer: 10-14 days
◉ What is the average life span of red blood cells. Answer: 120 days
◉ What percent of the differential should be comprised of neutrophilic
myelocytes, metamyelocytes, bands, and segmented neutrophils.
Answer: 50%
◉ True or False: Lymphocytes, monocytes, and plasma cells are not
counted in the differential.. Answer: False. All cell types are included in
the differential.
◉ What would the M:E ratio be with erythroid hyperplasia. Answer: 1:1
More RBC precursors present
◉ What would the M:E ratio be with myeloid hyperplasia. Answer: >5:1
More myeloid precursors present
